I've always found it very interesting how this ancient tradition evolved while still keeping true to it's origins. North America was largely settled by people from the isles, particularly Irish and Scotsmen, and the tradition adapted a native plant and it became a classic American tradition all it's own. Then to see that slight change in the ancient tradition spread from North America again, it makes you wonder how future anthropologists will interpret this change, whether they will understand all the cultural and social and economic dynamics that went into it.
